ESP8266 Community Forum

I've been trying to implement AES encryption on the ESP8266 using the Spaniakos AES library for Arduino and RPi (https://github.com/spaniakos/AES). The example code "aes" from the library does not run on the ESP as it involves a few avr library includes in the source code, but I isolated the main encryption and decryption parts of the library and managed to get a code compiling and running.

With my code I am able to define a plain text string, encrypt it with AES using a predefined key and IV and decrypt the result back into plain text (identical to the original plain text string). However, when I try to convert the same cypher text with online AES encryptors/decryptors with the same key the resulting text does not decrypt to the same original plain text. I also tried running the default "aes" example code on an arduino Uno, but got the same results.

Any help with this problem would be greatly appreciated.

Hello, have you moved forward? I am planning in my project to use AES as well, so I would be interested in to your library. Looking to your post, do you use correct encryption method? CRC/ECB/OFB ? Maybe this can be an issue.

hello there ,
spaniakos here.

i will be glad to help you mod the library for ESP8266.
actually i have an esp8266 for myself now, but i havent had the time to mode it.

thank you

@spaniakos Did you already modded your Library? If so, it would be awesome if you could post the link to it
